There is considerable interest among companies in claiming that their products can help avoid greenhouse gas emissions compared to other products in the marketplace. While it’s true that the use of some products can help to avoid GHG emissions, accurately measuring a product’s impact—whether positive or negative—can be challenging.

This paper discusses how governance of the global environmental commons requires collective action to generate public goods. Public goods theorists vary in their views about what it takes and how likely it is to achieve such collective action to produce these goods.

The paper uses two criteria to identify cities in the Global South that today are candidates for electrification – replacing fossil fuel–powered vehicles, stoves, furnaces and other devices with electric alternatives.

The world is already experiencing severe impacts of climate change, from extreme heat waves, sea level rise to species die-offs and crop failures. Must act quickly to stabilize global warming below 1.5° C (2.7° F) to avoid much greater threats, as the IPCC report released last October made crystal clear.

Urban areas are expected to triple in size between 2000 and 2030. Unmanaged urban expansion increases the costs of service provision, deepens spatial inequities, and imposes heavy economic and environmental burdens. New analysis on 499 cities’ urban expansion confirm the challenge of rapid outward expansion are greatest in lower-income cities.

In 2017 several leading climate analysis organizations came together as part of the Mission 2020 campaign to define six milestones—in energy, transport, land use, industry, infrastructure, and finance—that would need to be met by 2020 to bend the curve in global greenhouse gas emissions and put the world on a pathway consistent with the Paris Ag

This working paper seeks to provide decision makers at the city level a series of frequently asked questions and responses in order to assess the adoption and implementation of bike sharing.

India, the world’s fourth-largest greenhouse gas emitter, has pledged to reduce its emissions intensity per unit gross domestic product (GDP) by 33 to 35 percent below 2005 levels by 2030 through its Nationally Determined Contribution (NDC).

This case study in the World Resources Report, “Towards a More Equal City,” examines transformative urban change in Johannesburg, South Africa, through transit-oriented development (TOD). The paper reviews the evidence on whether Johannesburg’s TOD strategy has helped reduce spatial inequality in the city—and if so, how.

Parties to the Paris Agreement committed to “making finance flows consistent with a pathway towards low GHG emissions and climate-resilient development (Article 2.1c).” It is especially critical that energy-sector infrastructure is Paris aligned, given the large carbon lock-in potential of investments and the scale of investment needed in the co
