GHG protocol

Rio+20 and Its Shades of Grey

Copacaban PavementSustainable development always seems to come in shades of grey; excuses, obfuscation, conflicting demands, entrenched interests, and inertia can overshadow clarity on what needs to be done ‘on Monday morning’. But for some reason, like Rio de Janeiro’s iconic black slate and white marble sidewalks, sustainable development seemed to be a lot more black and white at last week’s big UN Conference on Sustainable Development.

Maybe it was the more than 20 hours that I spent stuck in traffic that helped bring clarity; or being one of the 50,000 visitors, each spending an average of $10,000 to travel, and emitting about 3.5 tonnes of CO2e (coincidentally what the global average annual per capita emissions needs to stay below, if we want to remain within a warming of 2° C). Flight delays getting there and back were more than 50 hours; leave alone the 24 hours in-the-plane. Was the Rio journey worth it?

UN Environment Programme, UN Habitat, World Bank Recognize New Global Protocol for Urban GHG Emissions, Encourage its Use

In March this year, we posted a blog on the draft edition of a global protocol for city-scale GHG emissions, announced jointly by ICLEI – Local Governments for Sustainability, C40, and the World Resources Institute (WRI).

Yesterday, a pilot version of the protocol was released at the UNFCCC climate meetings in Bonn, Germany. And today, UNEP, UN-Habitat and the World Bank expressed appreciation to ICLEI – Local Governments for Sustainability, C40, and WRI for this accomplishment. To learn more about the significance of the protocol, read this news feature.

Together Much is Possible – A New GHG Emissions Protocol for Cities

Factory smokestacks, EstoniaThis month marks an important milestone – an agreed to greenhouse gas (GHG) emissions protocol for cities was announced jointly by ICLEI – Local Governments for Sustainability, C40, the big-cities climate change club, and the World Resources Institute (WRI). The protocol builds on early work by ICLEI, WRI and WBCSD’s corporate scopes model, a research paper presented by Professor Chris Kennedy et al at the June 2009 Marseille Urban Research Symposium, and a joint UNEP, UN-Habitat, World Bank guideline, supported by Cities Alliance, launched June 2010 at the World Urban Forum in Rio de Janeiro.

Up to now there were many different types of ways that cities were measuring their GHG emissions. A few cities were leading. Rio’s one of the first cities to complete the new inventory. New York City, Amman, Cape Town, Tokyo and Mexico City are front-runners as well. Xiaolan and Kunming are lined up to be the first cities in China to use the new protocol. Soon, most cities that complete a GHG inventory will follow a common ISO standardized approach. This will make analysis and learning across cities much easier. A common and verifiable metric is also one of the best ways to attract additional finance for cities.
