Climate change, natural resource depletion and waste problems reveal the importance of natural resource saving. Resource-saving behaviour is necessary in order to enhance energy and water efficiency. By applying various theories of pro-environmental behaviour, researchers have recommended the main tools, such as financial, social and informational for the promotion of this behaviour. However, none of those works explored the impact of the proposed tools on the resource-saving behaviour. Therefore, this study showed the most effective tools, which can be regarded as the most important for policymakers. Furthermore, considering statements about the current level in respect of these tools, the aim of this study was to analyse the influence of declared financial, social and informational tools and real situations on resource-saving behaviour. Using data of the survey performed in Lithuania at the beginning of 2020, and by applying a new theory defined as “Assumptions and reflections of real situations”, the results revealed that according to citizens’ opinion, only the informational tool significantly determined the resource-saving behaviour. Social and financial tools had insignificant impact on this behaviour. However, the current level in respect of social and informational tools significantly affected resource-saving behaviour. Considering the financial tool, the results showed that only the money-saving aspect significantly determined resource-saving behaviour. A high price of resources did not motivate people to save natural resources. Therefore, this paper provided practical insights how effectively promote the resource-saving behaviour.

气候变化、自然资源枯竭和浪费问题揭示了节约自然资源的重要性。为了提高能源和用水效率，必须采取节约资源的行为。通过应用各种亲环境行为理论，研究人员推荐了主要工具，如金融、社会和信息工具，以促进这种行为。然而，这些工作都没有探讨拟议工具对资源节约行为的影响。因此，本研究展示了最有效的工具，可以说是决策者最重要的工具。此外，考虑到有关这些工具的当前水平的陈述，本研究的目的是分析宣布的财务、社会和信息工具以及实际情况对资源节约行为的影响。使用 2020 年初在立陶宛进行的调查数据，并通过应用定义为“真实情况的假设和反映”的新理论，结果表明，根据公民的意见，只有信息工具才能显着决定资源——储蓄行为。社会和金融工具对这种行为的影响微不足道。然而，社会和信息工具的当前水平显着影响了资源节约行为。考虑到金融工具，结果表明只有省钱方面显着决定了资源节约行为。资源的高价并没有激励人们节约自然资源。因此，本文提供了如何有效促进资源节约行为的实用见解。
