TAIPEI (REUTERS) - Taiwan has begun to assess how it can reach zero emissions by 2050, President Tsai Ing-wen said on Thursday (April 22), after green groups criticised the government for not doing enough to fight climate change.

Taiwan, though excluded from most international bodies and treaties due to pressure from Beijing, which considers the island as a breakaway province to be reunified, is keen to show that it is a responsible member of the international community.

On Wednesday, the European Union clinched a deal on a landmark climate change law that puts new, tougher targets on greenhouse gas emissions at the heart of its policymaking, to steer it towards zero net emissions by 2050.

China has also said it aims for a 2030 peak of carbon emissions, on the way to becoming carbon-neutral by 2060.

Speaking at an Earth Day event in Taipei, Ms Tsai said Taiwan "cannot fall behind the international trend".

She said: "At the moment many countries are discussing the target of zero net emissions transformation by 2050, and Taiwan is actively planning it."

The government, under the coordination of the Cabinet, had begun to assess and plan a possible path to reach a net-zero emissions target by 2050, Ms Tsai added.

While some might think this a challenge, many companies viewed it as an opportunity, she said.

"The supply and demand ends of the market must change the logic of their thinking, seize new business opportunities and strengthen Taiwan's competitiveness in the global supply chain."

Taiwan's previous target, set in 2015, was to halve emissions between 2005 and 2050.

Last year, Greenpeace called on tech powerhouse Taiwan to be much more aggressive in tackling climate change, in the face of the island's risks from extreme weather and rising sea levels.

Taiwan is suffering its worst drought in more than half a century after the typhoons on which it relies to replenish reservoirs failed to make landfall last year.
