To celebrate the recent World Food Day, learn how food production can be transformed from a greenhouse gas emitter to a carbon sink by improving soil biology.
“Climate is changing. Food and agriculture must too.” This year’s message from the United Nations Food and Agriculture Organization for World Food Day is timely as the planet emerges from yet another summer of record heat. With changing climates and increasingly frequent extreme weather events, the world is facing real challenges with food production, exacerbated by the declining capacity of soils to hold water, buffer temperature shocks, and supply nutrients to food crops.
Agriculture as a Climate Change Contributor
According to the Intergovernmental Panel on Climate Change, over a 20-year period, agriculture accounts for about 22 percent of global greenhouse gas emissions. This makes agriculture the largest contributing sector to climate change. In comparison, industry emits 20 percent of greenhouse gases, electricity and heat production 17 percent, and other energy–related activities another 17 percent.
Agriculture as a Climate Change Solution
There is good news, however. Because the agricultural system is a living community, its capacity for greenhouse gas sequestration can regrow organically under management practices that allow the soil ecosystem to recover and thrive.
To do this, farmers have ... Read More

Can a city be sustainable? That’s what our 2016 edition of State of the World investigates. In his chapter, “Reducing the Environmental Footprint of Buildings,” author and project co-director Michael Renner explains what actions cities can take to make their buildings greener.
Buildings are some of the biggest users of materials and water, consume nearly half of the world’s energy, and contribute almost half of global greenhouse gas emissions. With more buildings sprouting up every year and existing ones often being inefficient, cities have begun to tap into their toolkit of policies to help reach sustainability goals.
Four Methods That Work
Tapping into their policy toolkits, municipalities around the world are using a blend of building codes and permits, zoning regulations, building performance ordinances, and other mandates and regulations. Taxes and other financial policies can provide additional incentives. Subsidies can reduce the upfront cost of retrofits and ensure that lower-income residents are not left behind.
Here are four tactics that cities and their residents are using to push toward urban sustainability:
1. Building Certifications
Hundreds of green certifications exist today, ranging from standards for equipment and appliances (such as Energy Star and WaterSense) to certifications for entire buildings (such as BREEAM and LEED). ... Read More

Human nature often resists change. We struggle with moving from familiar surroundings to new, unknown territories. Yet, when it comes to the greatest single challenge we face today, our resistance to change will surely cause massive, uncontrollable, and unforeseeable changes.
Climate change is upon us. We know with certainty that our behavior is impacting the planet we inhabit. The last time atmospheric concentrations of carbon dioxide were this high was millions of years ago, long before Homo sapiens appeared. This places us in an entirely new era of risk, for which we have no precedent or reliable benchmark.
Climate change is the ultimate systemic risk. Its potential impacts will be global and will be disproportionately afflicted on the most vulnerable members of our civilization. Its profound disruptions will result in the indiscriminate extinction of species. Those who are most vulnerable to the changes brought on by climate change will be those who have least contributed to it.
Many individuals and organizations are considering divestment of fossil fuel companies in their investment portfolios. New York State Senator Liz Krueger proposed legislation for divestment of fossil fuel companies from its public pension funds, the Rockefeller Foundation announced their intention to divest, and more than 500 ...

A Changing Climate
By 2050, the world will consume 61 percent more energy than it does today. This should be good news, for, as access to reliable, affordable energy increases, so does the quality of life for hundreds of millions of people. Energy keeps schools and businesses running, computers working, cities shining, and cars moving. Without the availability of energy, the global poverty rate could not have dropped by more than half since 1990, allowing the opportunity to improve lives across a wide sphere.
Extending Progress to the Developing World
The developed world has seen great progress in renewable energy. Today, in the United States, virtually all new additions to power capacity come from sustainable sources. However, much of the future energy demand in the world will come from developing countries as they continue to grow and add more citizens to the middle class. This is perhaps one of the most difficult challenges that we face today. How can we ensure that the most threatening climate change consequences are avoided, but also ensure equitable access to energy? The answer, of course, is renewable energy, and the attendant electrification of products and services once serviced by fossil fuels.
The Leapfrog Effect
Unlike the United States, many ... Read More

“I came to the ocean to heal, but found an ocean that needed healing.” That was the realization that inspired artist Angela Haseltine Pozzi to dedicate her life to saving the sea. Her medium? Trash.
When Pozzi suddenly lost her husband, she took time to look for something meaningful and constant. Her search led her back to the Oregon shores of her childhood. There, she expected to find the familiarity and predictability of crashing waves. Instead, her life found new meaning and change.
As Pozzi walked along the Pacific shores, she found piece after piece of plastic littering the sand. Passers-by collected shells nearby, leaving the pieces of trash untouched. At that moment, Pozzi decided that the problem of ocean pollution could not be left ignored. She had been an art teacher—she knew how to motivate and educate. She decided to develop the Washed Ashore project to show that the plastic problem was real.
From Trash to Art
Washed Ashore is a massive undertaking. Pozzi works with a team of only nine people. Over the year, over ten thousand independent volunteers collect scraps of trash along 160 kilometers (100 miles) of the Oregon coast. ... Read More

The energy world is changing fast. Investments in renewable energy are outpacing investments in traditional energy. But both traditional power providers and startups are struggling to find viable business models for an industry in transition.
Among the first to feel the sweeping changes in the energy sector were utilities in developed countries that have a high share of renewables in the electricity mix. But now, more industries that rely on traditional energy sources are feeling the heat.
Shifting Toward Sustainable Energy
The overall business environment is shifting toward a clean energy future. In April 2016, 177 countries signed the ambitious Paris Climate Agreement. In response, companies are beginning to improve their sustainability footprint and are adjusting product portfolios and corporate strategies.
Despite the enthusiasm and well-meaning political support, it still seems difficult for businesses to thrive in this global energy transition. So far, the transition has undermined traditional energy markets without yet having created functioning new markets. Both risk-taking, disrupting pioneers as well as the asset-heavy, path-dependent incumbents are often at a loss.
Where Do We Go From Here?
Existing, large energy companies will find it difficult to succeed in the new energy future. They would have to risk a lot (but what is their alternative?). Yet their shareholders ... Read More

Greenhouse gas emissions from the transportation sector are growing faster than those from any other sector. With the transportation sector already accounting for nearly one-quarter (23 percent) of greenhouse gas emissions worldwide, investing in public transportation is a critical strategy to address global climate change.
Strategies to curb transport emissions, such as by transitioning to electric vehicles, depend primarily on pushing forward new efficiency-maximizing technologies for transportation networks and individual vehicles. Yet adoption rates have been slow, in part because vehicle owners and transportation providers lack the resources to finance the transition of their fleets.
How Can the Transportation Transition Begin?
Creative financing for the transport sector can be adapted from existing efforts to improve energy efficiency in buildings. The building sector has benefited from the involvement of ESCOs, or businesses that fund and install energy-saving equipment, charge the building owner a fee to pay back for this installation, and guarantee that the costs will not exceed the financial savings associated with the new product or system.
Who Could Champion the Shift?
A T-ESCO requires a handful of direct stakeholders, including: an entity interested and willing to play the part of the ESCO; a client or fleet manager interested in reducing energy consumption; and an ... Read More

“Today’s budget, unfortunately, continues the four-year stall in the province’s progress on climate action. While the costs of climate change were highlighted, any hint of the government’s new plan to respond to climate change was largely absent.
“The lack of direction is disappointing given the time the province has had to advance its Climate Leadership Plan. While we weren’t expecting the full details, we were expecting an indication of progress. For example, the budget could have indicated how the government will navigate the 2018 end of the carbon tax freeze, or how funds will be made available to pay for the investments that will need to be part of the plan.
“The premier talks about the importance of having the courage to say yes. With B.C.’s carbon pollution increasing, this government needs to quickly find the courage to say yes to climate leadership.”Read More

The Pembina Institute’s newest interactive map quantifies the number of jobs in B.C.’s green-building sector and pinpoints where energy-efficient homes and buildings are located in the province.
Released today to coincide with Buildings Day at the United Nations climate-change conference in Paris, the B.C. Green Buildings Map shows that this growing sector already employs tens of thousands of British Columbians. These jobs are found in both our biggest cities and our most remote communities.
The innovative companies in the green-building sector are literally the building blocks of the clean economy in the province, turning the climate challenge into an economic opportunity. B.C.’s government has taken steps to support this sector, but must take further and faster action to meet its greenhouse-gas emissions targets and accelerate the growth of the clean economy.
Homes and buildings use nearly a quarter of the electricity consumed in B.C. They also generate over 10 per cent of our province’s carbon emissions.
Last week, over 80 companies, organizations and cities threw their support behind the Call for Action on Energy and Climate in the Building Sector. The joint declaration urges the province to take bold measures to reduce emissions from homes and buildings.
