Laws to Tackle Climate Change Exceed 1,200 Worldwide: Study

Nations around the world have adopted more than 1,200 laws to curb climate change, up from about 60 two decades ago, which is a sign of widening efforts to limit rising temperatures, a study showed on Tuesday.

"Most countries have a legal basis on which future action can be built," Patricia Espinosa, the U.N.'s climate change chief, told a webcast news conference of the findings issued at an international meeting on climate change in Bonn, Germany.

She said the findings were "cause for optimism", adding that laws were one yardstick for tracking action on global warming alongside others such as investment in renewable energy or backing for a 2015 climate agreement, ratified by 144 nations.

The study, by the London School of Economics (LSE), reviewed laws and executive policies in 164 nations, ranging from national cuts in greenhouse gases to curbs in emissions in sectors such as transport, power generation or industry.
